BANGOR, Maine — Two men accused of three recent pharmacy robberies remained at the Penobscot County Jail on Tuesday night unable to make bail after making their first court appearances at the Penobscot Judicial Center earlier in the day.

Neither John D. Harmon Jr., 27, of Dover-Foxcroft, charged with the robbery Monday of a Bangor Rite Aid, nor John C. Campbell, 35, of Brewer, charged with two counts of robbery and one count of theft in connection with a robbery at the Brewer Rite Aid and a pharmacy at a Hannaford Supermarket in Bangor on Sept 29, entered pleas.

Superior Court Justice Ann Murray set bail for Harmon at $50,000 cash or $100,000 surety and at $3,000 cash or $30,000 surety for Campbell — the amounts requested by the Penobscot County district attorney’s office.

Assistant District Attorney Brendan Trainor told the judge he requested a much higher bail for Harmon due to his long criminal history, which includes three convictions for violation of conditions of release while on bail for other charges. Campbell has a limited criminal history, the prosecutor said.

Neither man brandished a weapon during any of the alleged robberies, Trainor said.

Harmon and Campbell both told Murray through the Bangor attorneys representing them at Tuesday’s hearings that they could not afford such high bails. Both men also asked to be treated for their drug addiction.

Campbell and Harmon are scheduled to make their next court appearances on Dec. 6.

Little new information about the three robberies was released Tuesday by police.

Harmon was arrested Monday by Bangor police on Webster Avenue North a little more than an hour after the Rite Aid pharmacy at the corner of Union and Fourteenth streets was robbed.

Police apparently tracked him to the location using a GPS device. It was in a pill bottle and was placed by the drugstore pharmacist in the bag with the drugs she gave to the robber, according to court documents.

Bangor police captured Jeffrey Macy, 46, of Eastbrook with the help of a GPS tracker on Sept. 30 after he allegedly robbed the same pharmacy, according to an earlier report.

When interviewed by Bangor police late Monday, Harmon denied he had committed the robbery, according to court documents. He later admitted he was the robber but said he was forced to do it to pay off a $7,500 drug debt.

Police took two other people into custody when they arrested Harmon. Information about whether they have been charged in connection with the robbery or other crimes was not available Tuesday.

Details about the robberies in which Campbell has been charged also were not released Tuesday.

Campbell fled Brewer soon after the robberies by boarding a Greyhound bus to New York, according to a previously published report. Brewer police Detective Fred Luce learned Sunday that Campbell had purchased a ticket to travel back to Bangor by bus.

He was arrested when he got off a Greyhound bus at Dysart’s in Hermon.

Details about where Campbell went and why he returned the way he did had not been filed at the Penobscot Judicial Center as of 4 p.m. Tuesday.

He told police Sunday he stole the drugs to feed his opiate addiction. He said he was unemployed and didn’t have access to health care, according to a previously published report.
